element里tree的setCurrentKey方法不生效，没有效果？

本文介绍: 要实现的效果，默认高亮选中<el–tree :data=”org a nOp t ion s” :props=”defaultPr op s” node–key=”part yId” :expand–on–click–node=”false” :filter–node–method=”filterNod e” hi g h li g ht–current=”true” ref=”tree1″ default–e x pan d–a ll @node–click=”handleNo

要实现的效果，默认 高亮 选中

在这里插入图片描述

&lt;el-tree
   :data="organOptions"
   :props="defaultProps"
   node-key="partyId"
   :expand-on-click-node="false"
   :filter-node-method="filterNode"
   :highlight-current="true"
   ref="tree1"
   default-expand-all
   @node-click="handleNode1Click"
   
 >
   <span class="span-ellipsis" slot-scope="{ node }">
     <span :title="node.label">{{ node.label }}</span>
   </span>
 </el-tree>

/** 查询部门下拉树结构 */
    getTreeselect1(id) {
      getCycleTree(id).then((response) => {
        const arr = []
        arr.push(response.data)
        this.organOptions = arr
        this.handleNode1Click(arr[0].hrOrganizationVoList[0])
		// dom渲染完成后执行
          this.$nextTick(()=>{
          	//默认选中
              this.$refs['tree1'].setCurrentKey(arr[0].hrOrganizationVoList[0].partyId);
          })
            
          
      })
    },
